i am currently testing 2 ice cold showers daily, as cold that you gasping for air, starting with head. i noticed improvement in every areas... seems to regulate hypothalamic sensory and push metabolism.

I had POIS before PSSD, the symptom was sadness after orgasm for next few hours, or maybe till next morning. And i can confirm that i tolerated very bad hot summers and warm showers, it was relaxing but i had fatigue after it. I had fatigue in summer temperatures 32-35 Celsius. Now i tolerate summer, i even don't feel the heat.

A 2007 study published by a molecular biologist named Nikolai Shevchuk found evidence that cold showers can help treat depression symptoms, and, if used regularly, might even be more effective than prescription antidepressants. “The mechanism that can probably explain the immediate mood-lifting effect of immersion in cold water or cold shower is probably the stimulation of the dopaminergic transmission in the mesocorticolimbic and nigrostriatal pathway,” Shevchuk said in a 2008 podcast with Neuroscene. “These dopaminergic pathways are known to be involved in the regulation of emotions. There is a lot of research linking these brain areas to depression.”
